Appendix A — Error Messages
A-1 Introduction
This Appendix provides a list of 3GPP error messages. Self Test and General Operation error
messages are in the User Guide.
A-2 3GPP Messages
Warning Messages
1. External Reference not found. Internal reference Locked successfully
This message is displayed when the instrument has detected an external reference but
couldn’t lock to the reference. It automatically switches to the Internal Reference. This
could happen if the external reference frequency does not match the specified external
reference frequency in the Setup menu.
2. External Reference Locked Successfully
Notifications
1. RF Over Power
2. ADC over range
a. If Auto Range is On - ADC over range: Decrease input power.
b. If Auto Range is Off - ADC over range: Adjust range or decrease input power.
3. Level Under
a. If Auto Range is On - No signal detected: Increase input power.
b. If Auto Range is Off: Adjust range or increase input power.
4. Out of band saturation
When the software detects that there is too much power outside the current frequency
range, this message is displayed. This usually means that the instrument is currently
tuned to a frequency with a very low amplitude signal or no signal and there is a strong
signal at another frequency outside the current IF bandwidth.
5. Poor Range
a. If Auto Range is On - Weak signal: Increase input power.
b. If Auto Range is Off: Adjust range or increase input power.
6. Lock Failure xx
When there is a lock failure detected from any of the internal LOs, this message is
displayed. The xx is usually an error code in hex that can be interpreted by a service
center to obtain more information on which LO had the failure.
7. Attempting to lock to Internal ref.
8. Attempting to lock to External ref.
